Controller action does not return detail view subpanels

I have added a custom button to a custom module in the Detail View, where the action is managed by the custom/modules/CustomModule/controller.php.

Action works fine, however at the end of the action function in the controller I have this line to make sugarcrm to return me the Detail View

$this->view="detail";

However this only returns (SugarcRM CE 6.5) the Detail View of the custom module, but not all of the subpanels in the view.... to get them I need to go go to the Menu item again and perform a search by the record.

What code do I have to introduce in the controller so once the action is finished sugar returns to the Detail View showing also the subpanles of the related modules??
